1. Main components: oil storage tank, power steering control unit, electric pump, steering gear, power steering sensor, etc., wherein the power steering control unit and the electric pump are a whole structure.

2. Working principle: The electro-hydraulic steering assist system overcomes the shortcomings of the traditional hydraulic steering assist system. The hydraulic pump used is no longer driven directly by the engine belt, but an electric pump. All the working states are calculated by the electronic control unit according to the driving speed and steering angle of the vehicle. Simply put, at low speed and large steering, the electronic control unit drives the electronic hydraulic pump to output high power at high speed, which makes the driver save direction; when the car is driving at high speed, the hydraulic control unit drives the electronic hydraulic pump at a lower speed. Operation, while not affecting the need for high-speed steering, while saving part of the engine power.

 

electric power steering system (EPS)

1. The full name of English is Electronic Power Steering (EPS), which uses the power generated by the electric motor to assist the driver in power steering. The composition of EPS, different cars, although the structural components are not the same, but generally the same. It is generally composed of a torque (steering) sensor, an electronic control unit, an electric motor, a speed reducer, a mechanical steering gear, and a battery power supply.

2. Main working principle: When the car is turning, the torque (steering) sensor will “feel” the torque of the steering wheel and the direction of the intended rotation. These signals will be sent to the electronic control unit through the data bus. The electronic control unit will be driven according to the transmission. The data signal such as the torque and the direction of the quasi-rotation sends an action command to the motor controller, so that the motor outputs a corresponding magnitude of the rotational torque according to the specific needs, thereby generating the power steering. If you don't turn, the system will not work, and it will be in the standby state. Due to the working characteristics of electric electric power steering, you will feel that driving such a car, the sense of direction is better, more stable at high speed, as the saying goes, the direction does not float. And because it doesn't work when it doesn't turn, it saves energy to a certain extent. Generally, high-end cars use such power steering systems.
